BGP failover to backup providers

I have 4 connections to different ISP's. We want to have one link that has the most bandwidth available route all of the traffic all of the time unless:

Peer state changes on the primary ISP link
or any event which would cause BGP to flap on this link

If the above failure occurs I would like to dynamically fail over to use the other links. I suppose we would then need to balance traffic across these other busrtable links. The cost on these links would be significant and that is why we only will use as backup in case of failure on primary.

What would be the best way to implement this type of configuration.


Thanks

Do you want to balance inbound or outbound traffic across your three backup links ?

Outbound traffic you have some control over, inbound traffic you don't have much control over (you either advertise it using BGP on a link or you don't).
